Dead Duck on Campus

Heading to Calypso for coffee (Purple Pickle was closed), I took the scenic route via the stepping stones behind the Sports Hall. I notice a flock of ducks on the oval (which was closed); more like a herd actually. Their numbers caused me to start thinking about the fact that I've never seen one of them dead! Amused, I trained my eyes at the surrounding bushes as I continued my walk. It wasn't long till I spotted what seemed like a dead duck! It had a white strip on its wing, so I thought maybe it was a magpie. But on closer inspection, it had a duck head. There it laid, belly up on one of the rocks beside the stepping stones. Its chest was ripped open such that you could see its spine (or some kind of bone). Obviously the result of an attack. Hmm... what animal attacks ducks? Cats? Dogs? No idea. But its my first Dead Duck sighting in The Australian National University!
